ABSTRACT:
An emulation system for emulating an application specific integrated circuit (ASIC) type microcomputer including a central processing unit, a user specific peripheral function unit and a user specific logic circuit, which are integrated together on a single chip. The emulation system includes a first integrated circuit for emulating the central processing unit, and second and third integrated circuits each of which comprises the ASIC-type microcomputer. Each of the second and third integrated circuits can selectively operate in a first evaluation chip mode in which the central processing unit and the user specific logic circuit are isolated from an internal bus, and in a second evaluation chip mode in which the central processing unit and the user specific peripheral function unit are isolated from the internal bus. The first integrated circuit is connected through an peripheral bus to the internal bus of each of the second and third integrated circuits. The second integrated circuit is put in the first evaluation chip mode for emulating the peripheral function unit, and the third integrated circuit is put in the second evaluation chip mode for emulating the logic circuit.
